It seems that your wireless card doesn't support PMF. And NetworkManager set it to required somehow. You can check whether it has the support by checking if at least CMAC or GMAC is available in the output of:
iw phy0 info | grep -A9 'Supported Ciphers'
Can you try whether this can work around the issue?
nmcli connection modify <connection> wifi-sec.pmf disable
